Nine-Year Follow-Up of Danish Chronic Fatigue Syndrome (CFS) Patients Impact on Health, Social, Vocational, and Personal Lives – Source: Journal of Chronic Fatigue Syndrome, vol. 14, #2, 2007

Objective: To determine quality of life (QOL) and health in Danish CFS patients 9 years after diagnosis.

Methods: Thirty-four adults with CFS responded to questions regarding QOL at diagnosis, and again 5 and 9 years later. At 9-year follow-up patients also responded to questions regarding health, fatigue, use of Health Care system, alcohol and exercise.


  • Two patients (6%) had recovered and 3 patients (10%) had received secondary diagnoses.

  • Overall, there was no improvement, except with depression/anxiety.

  • The order of severity among disabilities remained the same.

  • Work had the highest disability score, followed by post-exertional malaise.

  • Patients slept and rested 13.6 hours a day (mean).

  • Self-reported physical health correlated with hours sleeping and resting.

  • Rheumatic symptoms dominated the health symptoms.

  • Alcohol consumption was low, and the use of the Health Care system was modest.

Conclusion: After 9 years QOL was the same as at diagnosis, only mental health had improved.
